CARE International DSM Office now has Biogas

Posted on by

The 4000 litre digester/3000 litre gas holder CBS installed CARE International's kitchen at their head office in DSM

The installation of a 4000/3000 Compact Biogas System was completed at in Care International in Tanzania’s head office in November.   The CBS was installed at the staff kitchen and is hoped to be a viable alternative for the kitchen staff that had been using charcoal to cook lunch meals.

The aim of the installation is to eliminate the need for charcoal in the kitchen and save the kitchen the cost of purchasing bags of charcoal, which is costing them a minimum of 40,000 Tanzanian Shillings per month (30 USD).

CARE’s decision to install the CBS at their office also sets an important example to other institutions demonstrating that viable alternatives are available to reduce charcoal consumption, deal with urban organic waste and save money.

ARTI-TZ staff installed the system in October and after a month of training and troubleshooting handed over the system to the kitchen staff.  Training included teaching the staff about feeding, removing moisture from the main line, clearing up blockages in the feed pipe and proper use of the overflow effluent.

The team also supervised the cooking of lunch to determine how long the gas would last using a double burner cook stove.

After some initial trouble shooting the kitchen staff are getting accustomed to using the biogas and feeding and maintaining the system

After more than 2 hours the meals were cooked and the gas tank had only sunk half way.

While not all the staff were in the office the day it was tested we are keeping in communication with the kitchen staff to get some valuable feedback on the systems performance and to hear how much they have saved from not buying charcoal.

The final touch to the installation was to clean up the site around the CBS, removing garbage and sweeping leaves so that visitors can come and see the system for themselves, learn how it works and hopefully consider installing one in their home or institution.

Members of the Mbagala Development Association invested in a charcoal kiln, manual briquettes extruder and training in October/November of this year.  The groups 6 member governing body visited the ARTI-TZ office after hearing about the briquetting technology in the media.

After several visits and some research on the subject the group decided to invest in the equipment and training.  In November, ARTI-TZ trainer, Kennedy Mremi delivered the kiln to their site in Mbagala and spent a full day training them on how to pyrolyze dry biomass and convert the char powder into briquettes.

Initially the group will use the briquettes in their own home until the become comfortable with their use.  Once theyare accustomed to the briquettes they will begin to market them in their community.  The group will do this through a sensitization program.

ARTI-TZ will provide additional support in terms of training on packaging, branding, marketing, distribution and general business development.

Compact Biogas Systems offer considerable cost savings to institutions, such as secondary schools, office canteens, food processors, restaurants, and hotels that produce large quantities of food.  Using food waste as feed stock the CBS can replace or greatly reduce the large amounts of charcoal, firewood and/or LPG used in kitchens.

ARTI-Africa has installed several Compact Biogas Systems in secondary schools, safari lodges, orphan homes and offices in East Africa.  The systems, which are easy to maintain and feed offer energy dependence to the users.

Second School in Kigoma Receives Solar

Posted on by

The installation of a 2kw solar system at Nkundutsi Secondary School in Kasulu District, Kigoma region was completed on October 14th, 2010.  The dissigno Tanzania/ARTI-TZ team completed the installation after 10 days work.

The team installed 1kw to provide power to the three teachers houses and constructed a powerhouse to support an additional 1kw system to provide lights to the school’s classrooms and to support the charging station for Sun King solar lights that will be rented to the students for a cost cheaper than kerosene.

The team gives special thanks to the Head Master and the students in the newly formed Solar Committee who assisted with the entire installation process.

Orphans receiving solar lights donated by Kim and Jason Pineau

Going on safari in Africa has been a long time dream for Kim and Jason Pineau, but they wanted the experience to be more than just another vacation, they wanted to give something back.   In 2009 the couple from Orillia, Ontario, Canada decided to make that dream a reality.  They began researching and saving for a month long trip to Tanzania.  During this time they met up Dennis Tessier from ARTI-Tanzania who suggested to Kim and Jason raise funds so they can donate solar lights to orphans being cared for by Kidzcare Tanzania and for students in their early childhood education and nutrition project in Kyela, Tanzania.

With the help of friends and family Kim and Jason managed to raise enough funds to donate 55 solar lights.  The lights were handed over to the children during their visit to the home on October 18th.

Kim and Jason provide a perfect example of how one can give the gift of renewable energy.  Thank you for your support and kindness.
